First, your link says 80% think the name should stay so I am not sure where you want to go with your argument. 2nd, I already provided a link in an earlier post that I guess you skipped. Here it is for you...

Ok. fair enough I didn't see that. but im sure you also read this.

"Because they make up a very small proportion of the total population, the responses of 768 people who said they were Indians or Native Americans were collected over a very long period of polling, from October 7, 2003 through September 20, 2004".

So its a poll from people you SAID they were native American and only 768 at that. the whole article from the first link is just plain lie after lie. My wife has heard the slur called to her quite a few times. Its pretty simple really. Just because you haven't heard it doesnt mean it isn't a slur.
